∙ 10y agoIt means that the wave makes 25 complete cycles per second. Each up and down pass together is a cycle, so there are 25 sets of them in a second.

A floating leaf oscillates up down two complete cycle each second as a water wave passes by what is the waves frequency?
Say what! the question no makey sense to moi
How does the frequency of a water wave change as its wavelength changes?
With a water wave, an increase in the length of the wavelength will result in a decrease in the frequency of the wave. We could say that there is an inverse relationship between the frequency and the wavelength. As one increases, the other decreases, and as one decreases, the other increases.
How do you find the frequency of something?
You count how many times it happens in each equal period of time. Once you havethat number, you can say that the frequency of the event is that many per hour,or that many per year, or that many per minute.If it's that many per second, then the frequency is that many 'Hertz'.
Would it be correct to say that the Doppler effect is the apparent change in the speed of a wave due to motion of the source?
No, the doppler effect applies to changes in frequency.
Do sound waves make molucules move?
When you say "sound wave", you MEAN moving molecules.
A wave travels an average distance of 1 meter in 1 second with a frequency of 1 hertz Its amplitude is?
A wave travels an average distance of 1 meter in 1 second with a frequency of 1 hertz Its amplitude is that there is not enough information to say. A 60 vibration per second wave travels 30 meters in 1 second, its frequency is 60 hertz and it travels 30 meters per second.
What is the wavelength of 1.010 to the fifteenth power?
That number has no units, and just-plain-numbers don't have wavelengths. If you mean that number to have the unit of "Hertz", and to be a frequency of, say, an electromagnetic wave in vacuum, then it's wavelength would be 296.8 nanometers ... an ultraviolet wave.
What unit of measure is used for frequency?
You see, that is difficult to say for it can be measured in hertz or waves per second.(please improve this if I'm wrong but I think 10 hertz= 10 waves per second)
What does 60 cycles mean in electrical terms?
60 cycles is also called 60 Hertz. This is the frequency of the sine wave for AC voltage. It means there are 60 repetitions of the wave every second.Answer'60 cycles' is a lazy or slang expression for '60 cycles per second', which is a measure of the line frequency of North American electricity supplies (in Europe and elsewhere, it's 50). Under SI, the 'cycle per second' has been replaced by the 'hertz' (Hz). So we now say, '60 Hz'.

If the wavelength of light increases the frequency?
As the wavelength increases, frequency decreases. A wavelength is the distance from, say, a crest to a crest, or perhaps a trough to a trough. Frequency is essentially how many waves or how many cycles of a wave there are per unit of time, and we usually apply the term cycles per second or Hertz (which means cycles per second) to it.Wavelength is the physical distance the wave will travel as a single cycle of that wave occurs. And wavelength is a function of both frequency and of the speed of propagation of that wave. In any case, a longer wavelength is associated with a lower frequency. Increasing (lengthening) the wavelength decreases the frequency.
How are the energy and the frequency of an electromagnetic wave related?
For any point on the electromagnetic spectrum, the product of(wavelength) multiplied by (frequency) is 299,792,458 meters per second.That's the speed of the wave.
How does the frequency of a water wave change as its wavelength changes?
With a water wave, an increase in the length of the wavelength will result in a decrease in the frequency of the wave. We could say that there is an inverse relationship between the frequency and the wavelength. As one increases, the other decreases, and as one decreases, the other increases.
Well you can say that the frequency of DC is constant or not?
Yes it is constant at Zero Frequency. No, DC or Direct Current only means that the current only goes one direction, but it can have a frequency. You can have a square wave, sawtooth wave or sine wave that never goes from positive to negative or negative to positive and it would be a direct current with a frequency.
What does Mhz on cell phones mean?
MHz stands for Megahertz. Hertz is another way of saying cycles per second, or the frequency of a radio wave. So, if your cell phone works on 980 Mhz, it means that the signal is oscillating 980,000,000 times per second! To put this into perspective, your favorite FM radio station, say 104.3 is transmitting at 104,300,000 hertz. moving lower in the radio spectrum we can go down to AM radio and it transmits in KHz. Kilohertz or thousands of hertz. So 880 on your AM dial is transmitting at 88,000 hertz. Cordless phones and computers routers are typically in the 2.4 GHz region or 2.4 Gigahertz, meaning billions of hertz.
What is Mega Hertz?
Hertz is the SI unit for frequency. 1 Hertz equals 1 cycle per second. Mega is the prefix meaning 1 million. So one MegaHertz (MHz) is one million Hertz or one million cycles per second. When referring to say a computer processor running at 2000 MHz, this means that the core clock speed of the processor is switching (or changing state) 2000 000 000 times each second.
What determines the frequency of electromagnetic waves?
An EM wave is caused by an energy source, such as something as big as a supernova or something as small as an electron changing in speed. I would say the change in the energy level of the energetic particle that causes the wave determines the frequency of the wave. +++ Whilst you may be right about the quantum physics, the frequency of the wave is that of the energy source, be it in a star or a radio transmitter, driving it.
